Greek Chicken Sandwiches

I have had a love affair with tzatziki sauce from an early age. Sure, give me a good gyro, but I'm just as happy lapping it up with crackers, or sometimes even a spoon. This simple gyro-variation incorporates the fresh, light flavors of Greece (tzatziki included!) into a family- and budget-friendly meal. (Hint: Try it with Citrus-Glazed Fruit Salad!) 

½ cup balsamic vinaigrette

3-4 boneless, skinless chicken breasts

6-8 pita pockets or sandwich flats 

Sauce:

1 cup plain yogurt

1/3 cucumber, finely chopped

1 T. parsley

1 tsp. dill

1 garlic clove, finely minced

¼ tsp. salt

1/8 tsp. pepper

1 T. lime juice

Toppings:

1/3 cucumber, thinly sliced

1 wedge red onion, thinly sliced

Feta cheese, crumbled as desired

Place chicken in a large, resealable plastic bag; add vinaigrette and turn to coat; marinate 4 hours-overnight.

In a small bowl, combine all sauce ingredients. Refrigerate at least 1 hour to allow flavors to combine; stir before serving.

Preheat and spray grill; discard marinade and grill chicken until cooked through, about 5-7 minutes per side. Allow chicken to rest about 5 minutes, then cut into thin strips. Build each sandwich in a pita or sandwich flat, layering sauce, chicken, cucumbers, onion, and feta as desired.
